i had a 2010 smcwhich also leaked fuel at the gas cap especially when you're wide open throttle. LOL. I sold that 2010 to buy a 790 Duke. I kid you not that thing bored me after 6 months despite having 50 more HP. Sold the 790 and went back to a 690. Now im on a 15' 690 enduro with sumo wheels it doesn't leak fuel at the cap. :) I think it's worth updating the fuel cap parts to the next generation parts.
